Subject: [PATCH 09/12] ima: Use correct type for the args_p member of ima_rule_entry.lsm elements
Date: Mon, 22 Jun 2020 19:32:33 -0500 [thread overview]
Message-ID: <20200623003236.830149-10-tyhicks@linux.microsoft.com> (raw)
In-Reply-To: <20200623003236.830149-1-tyhicks@linux.microsoft.com>
Make args_p be of the char pointer type rather than have it be a void
pointer that gets casted to char pointer when it is used. It is a simple
NUL-terminated string as returned by match_strdup().
